Sakura is by no means "leagues ahead" of her colleagues.
She as of now has shown to use the Yin Seal and the remote healing technique.
The only thing she can do that is fit for battle is to channel her chakra into strikes (Because it was noted that she doesn't even have any raw strength that compliments the enhancements of infusing chakra into punches like tsuande)
Combat Wise she is not beating anyone from the K11
But,it's okay because she is not meant for battle.
She easily takes everyone in the k11 except:
Naruto, Sasuke, lee, neji, shino is debatable because his bugs are pesky.
However in terms of power and all of her skills as a ninja, she easily tops them all aside from (naruto and sasuke).
She is meant for battle, her chakra enhanced strength has been enough in the past. We have seen her be able to fight in combat. How dare you say she is not meant for battle. Her not having natural strength is a non factor because she is still able to pull off greater strength feats that ive seen with tsunade.
She is great offense and support abilities. One of the best support fighters now we see she can utilise katsuya as well. Not to forget chakra transfer and general healing.
Sakura is easily a combat type, she was even put into the short/mid range fighter squad in the war in the beginning as well. This is proof as if she was not seen fit she would have been in the medical division from the start.
Imagine when we see seal release from her? :3
K11 combat wise against Sakura:
Naruto > Sakura
Sasuke > Sakura
Sai < Sakura
Lee > Sakura
Choji < Sakura ( he can get big but she can hit hard, being big and slow is not working for him either)
Tenten < Sakura
Ino < Sakura ( ino is strictly support her jutsu are all 100% based on assisting)
Hinata < Sakura ( has been discussed many times among the base)
Shino >= Sakura (depending on the scenario)
Kiba >= Sakura (she should be able to beat him but people have been debating his 3 headed cerberus)
Neji > Sakura ( to me neji is just like hinata but he has shown better combat ability and speed, ill let him have it)
